Step 5: Explain the energy change in the reaction. a) Create a new blank document. Type your name at the top.
b) Write a few paragraphs describing the chemical reaction and explaining the energy change in
the reaction. Your document should:
i. identify the reactants and products.
ii. describe the change in energy that occurs as bonds are broken and formed.
iii. identify how the potential energy of the reactants compares to the potential energy of
the products.
iv. state and explain the net change in enthalpy.
v. identify whether the reaction is endothermic or exothermic.
vi. explain how energy is conserved between the reaction and the surrounding
environment.
This is the initial chemical equation: C3H8 + O2 = CO2 + H2O This is the balanced chemical equation: C3H8 + 5 O2 = 3 CO2 + 4 H2O
